    Abstract: Disclosed are an antimycin compound and a preparation method and use thereof. The preparation method comprises: fermenting a marine actinomycete (Streptomyces sp.4-7) with a preservation number CCTCCNO: M2020953 to obtain a fermented product and soaking and extracting the fermented product with ethyl acetate to obtain a crude extract; and carrying out separation and purification by normal-phase silica gel column chromatography, reversed-phase MPLC, and semi-preparative reversed-phase high-performance liquid chromatography. The invention has the advantages of resistance against Botrytis cinerea and Penicillium citrinum.

    Abstract: The present invention relates to an anti-inflammatory use of macrolactin compounds such as macrolactin A, 7-O-malonyl macrolactin A and 7-O-succinyl macrolactin A, which are produced from a novel Bacillus strain of Bacillus polyfermenticus KJS-2 (KCCM10769P). The macrolactin compounds provided by the present invention were confirmed to greatly suppress the expression and formation of inducible nitric oxide synthetase (iNOS) and cyclooxygenase-2 (COX-2) which are proteins related to the formation of inflammatory mediators, and to accordingly inhibit the formation of nitric oxide (NO) and of prostaglandin E2 (PGE2) which are the metabolites of the proteins. In addition, the macrolactin compounds provided by the present invention were confirmed to have excellent effects in inhibiting the formation of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and granulocyte macrophage colony-stimulating factor (GM-CSF), which are pro-inflammatory cytokines. Therefore, the macrolactin compounds produced by the Bacillus polyfermenticus KJS-2 strain according to the present invention can provide excellent anti-inflammatory agents.

    Abstract translation: 本发明涉及由新生芽孢杆菌(Bacillus polyfermenticus)KJS-2(KCCM10769P)的芽孢杆菌菌株生产的大多数内消旋用途的大多数乳糖素A,7-O-丙二酰基大内酰胺素A和7-O-琥珀酰基大内酰胺素A )。 证实本发明提供的大内酰胺化合物能够大大抑制与形成炎症介质相关的蛋白质的诱导型一氧化氮合成酶(iNOS)和环氧合酶-2(COX-2)的表达和形成,并因此抑制 形成一氧化氮(NO)和作为蛋白质代谢物的前列腺素E2(PGE2)。 此外,本发明提供的大多数内消旋化合物被证实在抑制肿瘤坏死因子-α(TNF-α),白细胞介素-1和bgr的形成方面具有优异的效果。 (IL-1和bgr),白介素-6(IL-6)和粒细胞巨噬细胞集落刺激因子(GM-CSF),其是促炎细胞因子。 因此,本发明的由芽孢杆菌属多发性支原体KJS-2株产生的大分子内酯化合物可提供优异的抗炎剂。
